Introduction: Adequate sleep may help regulate emotions, which in turn may influence moral decision-making. Therefore, the aim of the current study was to examine the relationship between sleep quality, emotion regulation and moral decision-making.
Method: In this descriptive online survey, we administered three questionnaires, including the Pittsburgh Sleep Quality Index, the Emotion Regulation Questionnaire, and the Moral Decision-Making Questionnaire, to 306 non-randomly selected employees of the Iranian National Tax Administration who were surveyed via the Internet between December 2021 and January 2022.
Results: Analysis of data based on Kendall's Tau correlation coefficient showed no significant relationship between sleep quality with emotion regulation and decision-making and most of their subscales. Only a weak direct relationship was observed between some indicators of poor sleep quality (poor subjective sleep quality, sleep disturbances, and use of sleep medications) and utilitarian low-conflict direct moral decision-making.
Conclusion: According to findings it can be stated that for people who have sufficient cognitive capacity, time to manage their emotions, and access to society's established moral values, poor sleep quality may not be significantly associated with poor emotion regulation and moral decision-making.
